Observation of Fracture Surface of Crushed Particle by Scanning Electron Microscope

Abstract

By the observation of fracture surfaces of single spherical particles we obtained the following results, 1) the fracture surfaces of specimens of glassy materials were mainly of concoidal structure, 2) the status of fracture surface of mineral specimens having incomplete cleavage was quite irregular and 3) the specimens of minerals having complete cleavage were fractured along to their cleavage plane.
